Hacking group OurMine has claimed responsibility for many of these hacks.

It does not appear to be behind the hacking of Mr Iribe's Twitter page though.

His account was compromised on 29 June, with the hacker announcing himself as the "new CEO" of Oculus and questioning why the chief executive behind "such cool technology" had been using a four-year-old password.

The hacker later told technology news site Tech Crunch that he had accessed the password via a MySpace breach.

Hundreds of millions of hacked account details from MySpace and Tumblr have been advertised for sale online in recent months although those breaches were several years ago.
